Schneider Acti9 iID K 25A 4P 30mA RCCB (A9R50425) is an option among residual current circuit breakers at Bashiti Stores, intended for detecting residual current and tripping the circuit when the specified leakage sensitivity is exceeded. This model has a 25A rating and 30mA leakage sensitivity. When comparing, distinguish between the current passing through the device and the leakage value that triggers a trip, and review the appropriate protection type for the loads.
Practical Benefits
- Adds residual current detection functionality to the protection system when selected and installed correctly.
- The presence of a specific rated current and leakage sensitivity allows for clear comparison of the device against panel requirements.
- Distinguishing between protection type and current helps avoid confusion between wiring protection and leakage protection.

Who Needs This Product?
Technicians preparing and maintaining distribution panels in buildings, when residual current protection is required according to the protection plan. The type, sensitivity, current, and number of poles must be selected in coordination with other breakers and loads.
Installation and Verification — For the Professional Technician
The following steps outline the general workflow; the manufacturer's diagram for reference A9R50425 must be followed to determine terminals and connection values. Work must not be performed on a live circuit.
- The technician disconnects all power sources and secures them against accidental restart, then verifies the absence of voltage with a suitable tool.
- Matches the device reference, number of poles, current, and voltage with the panel diagram, and reviews conductor cross-sections and protection coordination.
- Mounts the component on the rail or its designated position after ensuring compatibility, and identifies supply and output from the manufacturer's diagram for this reference.
- Performs connections according to the tightening torque, stripping length, and wire cross-sections specified in the model manual; these values should not be taken from a similar device.
- Checks the tightness of the installation and connections, closes the covers, and conducts the required operational and protection tests before handing over the circuit.

Frequently Asked Questions Before Purchasing
Does an RCCB protect against overload and short circuits?
The RCCB does not include overcurrent protection, therefore it requires coordination with a suitable circuit breaker or fuse. It should not be used as a substitute for an overload and short-circuit breaker.
Does 40A mean the leakage sensitivity is 40A?
No. The rated current and leakage sensitivity are two different values; sensitivity here is indicated in milliamperes (mA), while the rated current concerns the current flow through the device.
Is the AC type suitable for all electronic loads?
Not automatically. The technician determines the required protection type based on the shape of the potential leakage current and the nature of the loads, and some circuits may require a different type.
